This is a genuine Subaru EJ257 2.5 liter fully loaded and pre-balanced short block. This is a great option for STI owners that may want to build a spare motor or who need to replace a damaged motor. The full rotating assembly comes balanced, sealed and loaded with an OEM crank, rods and pistons-- just bolt it up, break it in and you are good to go.
- THIS IS NOT A COMPLETE MOTOR: This is a fully assembled bottom end, which consists of a block, crank, rods and pistons only. You will need to reuse your stock cylinder heads or purchase replacements.
- For high-powered applications, we recommend replacing the cast OEM pistons in this block with CP Forged OEM-size units
- For shipping outside of the continental US, give us a call.
Warranty Disclaimer:Subaru of America will only warranty parts installed on a car that has a matching VIN to that part.
